Abstract
The research details the design and development of a spreadsheet based
software system that has been built using the principles of Monte Carlo simulation. The simulation has been applied to a residential building with a certain number of rooms, each with specific characteristics pertaining to volume, occupancy,
and thermostat set point. The consideration of variables related to the building
envelope and weather, and the HVAC system have provided a realistic view that
enables the accurate estimation of annual energy usage and costs. The main findings of the research are reflected in the sensitivity analysis that estimates energy
use and cost based on variance in the set point of thermostats that operate based
on occupancy levels in various times of the year when the weather pattern could
change drastically with respect to time, under the inherent weatherization levels of
the building. The most important conclusion is that, upon analyzing the results of
the sensitivity analysis, specifically with respect to the operations of the thermostats and occupancy levels under constant building envelope characteristics, decision makers will be able to incorporate energy efficiency measures and
infrastructure improvements over time, in order to save energy and cost.
